ABSTRACT:
A fin (1) suitable for stabilizing the flight of a projectile for example, is formed with an integral cantilever spring member (4). The fin (1) is rotatable about a pivot (3) from an initial stowed position (not shown) to a deployed position. The spring (4) is initially retained against the fin (1) but when it is released, the fin is forced outwards to its deployed position by the action of the spring (4), the free end of the spring moving into engagement with a surface (7) to retain the fin in the deployed position.
